Chad McDonald, O.D. – Optometrist

Have you ever met a native Mainer you didn’t like?

Dr. Chad McDonald’s enjoyment for the New England way of life comes from his roots in rural Jay, Maine. Now living in the Newburyport area, he enjoys the quaint atmosphere and variety of activities coastal New England has to offer.

A graduate of the University of New England in Biddeford, Maine and the New England College of Optometry in Boston, Dr. McDonald distinguished himself for superior patient care, graduating with honors in primary care, contact lenses, pediatrics, and low-vision care. In 2013 Dr. McDonald became Newburyport’s first Board Certified Diplomat in the American Board of Optometry.

Dr. McDonald completed his residency training with the Boston Medical Center and the Massachusetts Eye and Ear Infirmary. At the Lighthouse Center in New York City, he furthered his education in comprehensive care for the visually disabled. Dr. McDonald became a partner in the Watts Eye Associates practice in 1999.

Dr. McDonald is a member of the Massachusetts Society of Optometrists and the American Optometric Association, served as a Senior Examiner for the National Board of Examiners in Optometry, is a former Adjunct Clinical Faculty member of the New England College of Optometry in Boston, is a past board member and past president for the Newburyport Lions Club, and enjoys the excitement of serving as chairman for the annual Bed Race during Yankee Homecoming week.

Outside the office, he likes spending time outdoors with his family. His wife is Dr. Rebecca Boyer, an OB/GYN physician practicing with Women’s Health Care of Newburyport and Haverhill. They have two sons. Dr. McDonald is a self-described sports junkie, as he enjoys rooting for all the Boston sports teams! He enjoys road and mountain biking. His dream vacation would be to go to all of the U.S. National parks. Outside of the office Dr. McDonald enjoys taking a long bike ride or a day of hitting the slopes, making a playlist of his favorite tunes, or watching a good movie. He is a big fan of classic rock, but his favorite song is “Ordinary” by the Alternate Routes. His favorite frames are Randolph because they are made in the USA. He is known in the office for his famous homemade cinnamon rolls- from his grandmother’s recipe!

Dr. Sullivan grew up in the greater Newburyport area and as a child had her first eye exam at Watts Eye Associates.

Dr. Sullivan lived in San Francisco for a year between college and optometry school, and wants to take a trip back out there! Outside of the office, Dr. Sullivan spends time with her husband and two boys- often to many sporting events. The two boys exhaust but recharge her at the same time. She loves going to the beach, and could stare at the ocean for an indefinite amount of time. Her theme song changes by the week, and she needs coffee every morning to function! She would love to go to Alaska and South America with her family. She enjoys reading- mainly fiction, and trips up to Stowe, Vermont. Her favorite frame lines are MODO, Vera Wang, Maui Jim and Oakley- now she is thinking she needs new frames!

She also recharges by spending time on the beach (any beach will do) and taking in the sight of the ocean. Her theme song is “Sweet Caroline” by Neil Diamond- she sings it to herself sometimes as she is organizing the wide variety of frame displays we have.

Sarah has been working here since she was 12 as a cleaning assistant! She cannot live without coffee- iced coffee, with cream only- NO sugar! She enjoys walking downtown with her kiddos, to get coffee and to the playground. Sarah enjoys laughing with the team the most while at work! Her theme song- David Bowie’s “Heroes” playing in the background while relaxing in a thatched hut in Bali would be a dream. She loves looking through her Bellinger frames because they are so unique, and watching sunrises over the beach.

Leanne Kierstead, CPOA


Leanne has been with the practice since 2006. She was looking to change careers, and the girls at the desk at the time suggested she apply here! Leanne runs on chocolate, and enjoys her time out of the office at the beach with her family. While at work, she lends a hand helping with all areas of the practice, and enjoys making connections with patients and keeping tabs on those she has seen for years! Her favorite frame line is Fysh because it is beautiful and different. She recharges on the beach, and her favorite sight to see is the sun over the water.

Her favorite frame lines are Diva and Fysh because of their styles and colors! While out of the office, Tara loves going on whale watches, taking candid photos of her nieces and nephews, and helping out in different areas within her church.

Fanny started at WEA in March of 2014 as a technician- doing pretesting and taking care of patient medical histories. Fanny really enjoys getting to know our patients and taking care of them. Originally from the Dominican Republic, she enjoys going home and taking in the view from her Grandfather’s porch. From that porch you can see the mountain and the blue of the sea as far as the eye can see! Her theme song is “Todo se lo debo a el” by Marcos Yaroide- it speaks of how many blessings we have in our lives. Out of the office, Fanny loves going to the beach and visiting the DR, but dreams of visiting Italy, Spain, France, and Iceland!

You can see his passion for this line of work with his interactions with the patients and our team. He thoroughly enjoys traveling and hopes to get back to Europe soon. He loves ’60s and ’70s music, and cannot pick just one favorite frame line. He is known in the office as being a gentleman, and always looks dapper! He cannot function without his good health!

Cue the 80s music for this lady to get the day going! Tracy is our scheduling and insurance guru, making sure to have all of the information ready, so all patients can get the most of their benefits! Exploring Iceland and the amazing natural springs would be her dream vacation! Vera Wang and MODO are two of her favorite frame lines, as they have some really fun designs. Much to her co-workers’ dismay, she is known for bringing in bizarre breakfast foods. With 13 years under her belt here at WEA, she brings funny stories and many great cackles and snorts to our practice.

Jay Oczkowski, RDO

Licensed Optician

Jay started working at Watts Eye in May of 2016. He is known around the office for being the “class clown” and always has something funny to say to brighten everyone’s day! He starts every day with a large iced coffee and is ready to be a jack of all trades in the optical lab! He loves helping people pick out the best frames for them, and takes the time to make them with love. Kite-surfing is his out of office getaway, and his dream vacation would be to go to Bora Bora and Tahiti to kite in the gorgeous turquoise waters. His theme song is ACDC “Highway to Hell”- that paired with a rumrunner in hand and a seat in the sand is how he recharges! His favorite frame line is iGreen because of the bright and fun colors and their lightweight designs.

Sarah Corl, CPO

Sarah began working at WEA in January of 2016. She enjoys working with the many social media outlets, and lending a hand in helping people select frames that make them feel great! She survives on coffee and mascara- as she is known in the office for her lashes. Her time out of the office is spent on the rail trail walking her dog Ryder, and spending time on the water or on the beach- which is also how she recharges! Her favorite frame lines are MODO and Fysh because they are stylish and bold. Her dream vacation would be to go to Mykonos and Santorini, Greece and take in the beautiful blue waters. Another dream spot is Reykjavik, Iceland to take in the Northern Lights in a glass igloo- it would be magical to see all of those amazing colors!

Cinthia Proano

Cinthia started working at WEA in November of 2016. She is our Ecuadorean transplant, and studied in Ecuador for her Medical Schooling and Ophthalmology. She studied the cornea at Harvard in 2002!

She thoroughly enjoys teaching, and even prepares slides and lectures for the staff meetings. Out of the office, Cinthia loves to play, sing and hear music- as she plays the violin! She also enjoys swimming, and would love a chance to get back to the Galapagos Islands to take in the beautiful views and swim. To recharge, she prays, and the peace of God fills her up. Her favorite song is “I can only imagine.”

Sydney Derepentigny

Patient Care Coordinator

Sydney joined our team in November of 2017. She cannot function without her morning cup of coffee- and enjoys meditating to recharge.
